The Forge Freeze fires a beam of cold energy, freezing zombies in a solid mass of ice. The weapon is able to fire a pulse that can shatter the frozen enemies, but they can also be shattered using melee, gunfire, or explosives.

Notably, frozen zombies can be killed with a single melee hit on any round. The Forge Freeze also has a built-in Fusion Mag, allowing it to automatically regenerate energy when depleted. However, the Forge Freeze cannot be manually reloaded.

When upgraded in the Pack-a-Punch Machine, it becomes the Frostbite, gaining increased damage, an increased magazine size, and more reserve ammo.
